That GPS jammer is a hoax - it doesn't work. But, if you can sell them to Iraqis for thousands of dollars, I guess they work just fine!!

Unless, of course, you happen to know a thing or two about GPS. This might help, you can also check the FAA web site (look in the ATC issues section).

Something always jams my GPS receiver while driving from Detroit, North, to Flint City Michigan. It goes on for about 30 miles. GPS are based on simple redio waves. Anything that overpowers those waves, and makes them unreadable, on that frequency will jam it. Not a difficult task.

Actually they do work that has been a probem for people in the biz for some years. To address this, development of "anti spoofing modules" differential GPS and RAIM criteria has minimized it considerably. All of this is in place in our aircraft and weapons. With enough RF power any receiver can be driven into saturation or excessive error rates.
